3 Why economics? Successful strategies to scale up and spread complex community-level interventions require an understanding of the resources required for implementation, how best to distribute them among supporting institutions, and how resource consumption and distribution varies across settings.

4 Failures in public health implementation Many evidence-based public health strategies reach less than half of U.S. populations at risk: Smoking cessation Influenza vaccination Hypertension control Nutrition & physical activity programs HIV prevention Family planning Substance abuse prevention Interpersonal violence prevention Maternal and infant home visiting for high-risk populations

5 What gets implemented in public health? Organized programs, policies, and laws to prevent disease and injury and promote health on a population-wide basis Communicable disease control Chronic disease and injury prevention Epidemiologic surveillance & investigation Community health assessment & planning Public education and communication Environmental health monitoring and assessment Enforcement of health laws and regulations Inspection and licensing Inform, advise, and assist school-based, worksite-based, and community-based health programming and roles in assuring access to medical care

6 Economics & public health implementation >75% of US health spending is attributable to conditions that are largely preventable Cardiovascular disease Diabetes Lung diseases Cancer Injuries Vaccine-preventable diseases and sexually transmitted infections <5% of US health spending is allocated to prevention and public health CDC 2008 and CMS 2013

9 1 - National Longitudinal Survey of Public Health Systems Cohort of 360 communities with at least 100,000 residents Followed over time: 1998, 2006, 2012, 2014 Measured from local public health official s perspective: Scope: availability of 20 recommended public health activities Network: types of organizations contributing to each activity Effort: contributed by designated local public health agency Quality: perceived effectiveness of each activity Linked with organizational and financial data from NACCHO s National Profile of Local Health Departments

18 2 - Multi-Network Practice and Outcome Variation Examination Study (MPROVE) 6 states 305 community settings Identify implementation measures high-value services: Chronic disease prevention Communicable disease control Environmental health protection Create registry of measures: consistent across communities Profile geographic variation in the delivery of selected public health services across local communities Decompose variation into attributable components: need-sensitive or preference-sensitive factors supply-sensitive factors Examine associations between service delivery & outcomes

19 3 - Public Health Delivery and Cost Studies (DACS) 11 states 250 community settings Adapt & apply established cost measurement/estimation methodologies to public health settings Identify the costs of implementing selected high-value public health services Assess how costs vary across institutional and community settings Examine the determinants and consequences of variation in the costs of implementation Economies of scale and scope Efficiency & productivity Equity

20 MPROVE measurement dimensions Availability/Scope: specific activities produced Volume/Intensity: Frequency of producing activity over period of time Capacity: Labor and capital inputs assigned to an activity Reach: Proportion of target population reached by activity Quality: effectiveness, timeliness, equity of activity Efficiency: resources required to produce given volume of activity

21 DACS cost estimation methods Retrospective cost accounting methods - Modeling and decomposition using administrative records - Surveys with staff and/or administrators Concurrent actual cost methods (micro-costing) - Time studies with staff - Activity logs with staff - Direct observation Prospective expected cost methods - Vignettes - Surveys with staff and/or administrators - Delphi group processes
